FRICTION-TOP can.

Application filed April 19, 1920.

1 0 all whom it may concern:

Be it known that I, GEORGE A. LnIoH'roN, a citizen of the United States,residing in Roslindale, in the county of Suffolk and State ofMassachusetts, have invented a. new and useful Improvement in Friction-Top Cans, of which the following is a specification.

This invention relates in general to friction top cans and has for itsobject broadly the provision of a friction top can, the friction top orplug of which may be readily pried off or removed by the use of a coinor any handy tool or implement.

An important object of the invention is the provision of a can of thischaracter, the top and body of which will be so con structed that thecover may be pressed down tightly to closed position without renderingdiflicult the insertion or manipulation of the coin or tool and withoutdanger of inaccurate engagement of the interengaging friction walls ofthe cover and body.

Another important object of the invention is the provision of a can ofthe character described and having the advantages mentioned, which willprovide a full face smooth surface of the top when the latter is beingpushed into closed position.

Another important object of the invention is the provision of a top forsuch a can, which can be easily and cheaply manufactured and which maybe safely handled without danger and which can be used with any bodyhaving an opening of appropriate dimensions to receive it.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which takenin connection with the accompanying drawing discloses a preferredembodiment thereof.

Referring to the drawing.

Figure 1 is a. perspective view of a can embodying my present invention;

Fig. 2 is a transverse sectional view taken on the central axis of thecan shown in Fig. 1; and

Fig. 3 is a partial side elevation thereof.

For the purpose of illustrating my present invention I have shown on thedrawing a can body formed of a cylindrical wall 11, closed at its bottomby a suitable closure 12 and having an inwardly extending an- Serial No.374,795.

nulus 13 at the top seamed at 14 to the upper edge of the wall 11. Thisannulus is bent up at 15 to a horizontal or flat portion 16 andtherebeyond to provide a friction wall forming flange 17 extendinginwardly of the can body.

The top or friction plug consists of a central circular part 18surrounded by a substantially cylindrical portion 19 which provides afriction wall for engagement with the friction wall 17 of the annulus. Ashoulder 21 is provided above the friction wall 19 and extends outwardlycontinuously around the top for engagement with the horizontal part 16of the can body. The top is provided with an outwardly extending pry-offflange 22 spacedabove the shoulder 21 by a vertical cylindrical portion23, said pry-off flange being bent back upon itself as indicated at 24in Fig. 2.

The interengaging parts of the cover or top and the body, i. e., theshoulder 21 of the top and the fiat portion 16 of the body, space theflange 241 above the part 16 ofthe body evenly and at the requireddistance and insure accurate engagement between the interengagingfriction Walls.

It will be manifest that the can described can be cheaply and easilymanufactured! and that the tops, being strong, are not easily damaged inshipment and handling.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing without further description, andit will will be apparent that various changes may be made in the form,construction and arrangement of the parts described without departingfrom the spirit and scope of the invention or sacri' flcing any of itsmaterial advantages, the form hereinbefore described being merely apreferred embodiment thereof.

I claim:

A friction-top can, comprising a body provided at its top with aninwardly extending annulus the outer part of which is cylindrical part,with a larger and outer cover. having an outwardly extendingcylindrical, part, between which cylindrical; flange which. is spacedabove the bent-up parts is a shoulder adapted to engage on part of saidannulus by means of said 10 top of said annulus Whenthe can is fullyshoulder, the said outer cylindrical part be- 5 closed and thereby limitthe insertion of ing of less diameter than said'bent-up part thefriction seat Wall of the cover Within and said flan e. the frictionseat wall of the annulus, the ErEORGE A, LEIGHTON.
